Astrophil and Stella: Sonnet 27

Because I oft in dark abstracted guise
Seem most alone in greatest company,
With dearth of words, or answers quite awry,
To them that would make speech of speech arise;
They deem, and of their doom the rumour flies,
That poison foul of bubbling pride doth lie
So in my swelling breast, that only I
Fawn on my self, and other do despise.
Yet pride I think doth not my soul possess
(Which looks too oft in his unflatt'ring glass):
But one worse fault, ambition, I confess,
That makes me oft my best friends overpass,
Unseen, unheard, while thought to highest place
Bends all his powers, even unto Stella's grace.
